Closely allied with the work of the Department of Agriculture is the irrigation service, which is reclaiming millions of acres of land otherwise useless, by furnishing it with unfailing water. The National Forests are under the direction of the Department of Agriculture, which employs about two thousand rangers and fire look-outs.[A] The Biological Survey has successfully found methods for destroying the rats, chipmunks, mice and ground squirrels which cause losses of many millions to the farmers. Millions of copies of printed circulars and pamphlets on various phases of farming are printed. No agency of the Government reaches so great a number of the active workers and producers of the land.

They were keen on the Indian fur trade, and produced salt meats, grain “naval stores,” (pitch, tar and turpentine), potashes and pearl ashes, timber, and other things, and sold them to European countries. In return they imported calicoes and “oznabrigs” (which were a kind of linen) “paduasoy” (which was Italian silk), hardware, guns, tools, china, and the rich cloths, velvets and satins which Colonial gentlemen delighted to wear. When the United States came into being as a Government, it paid very little attention to commerce, leaving the merchants free to develop their trade with all parts of the world. It is only in recent years that Uncle Sam has realized how he can help the merchant, the shipper and the vessel owner. Not until 1903 was there an office at Washington charged with the duty to “promote foreign and domestic commerce.” Not till 1913 was there a distinct Department of Commerce, within which were grouped some of the most important services rendered by the nation to its people. For example, commerce includes such varied services as lighthouses, steamboat inspection, fisheries, navigation, and the coast survey. In addition the Department of Commerce comes very near to the complicated organization of the business of the country, through its Bureau of Corporations, Bureau of Standards of Weights and Measures, and Bureau of Foreign and Domestic Commerce, as well as the Census Bureau, which collects a variety of statistics.
